Back then the hot  deal with aquarium keeping was under-gravel filters.   work great to keep the aquarium clean but are death on planted plants.      I had Chiclids  Some are notorious diggers.   Oh Yeah Salt water tanks were big even then...   I imagine some were made of stainless for corrosion resistance.
I still have my 110 gallon For that tank I used a combo of an under gravel filter and a canister filter.   Too deep for one that hangs on the back.   The shape also dictates needing a good exchange rate and Air stones to stir the surface up.  Air bubbles let carbon dioxide out.
I may buy a smaller more conventional tank for Raising Tilapia.   Easier to deal with I could get one on Craigslist....    Yep I think that's a good idea.  I can raise natural food for the fry in the form of Daphnia.  Water fleas...    And another tank for brine shrimp...
Here is a picture of my horse....   I still have her.   Shes being cared for at a retirement facility.  Shes been there two years now while I get back on my feet.
		
		
	
	
In her prime she was about 1700 pounds...   When I brought her home she went up to 2000 pounds.   LOL   But shes 25 now and shes hovering around 1800.   Which is a decent weight for a horse that does nothing... LOL  
Yep thats me...   With the help of a trainer we trained her for Riding and Driving.  I have ridden her about ten times.    I have driven her many many times...   I have a forecart and used to have a show cart...  Forecart is very heavy I need help hitching it.   The show cart was too big.  
What I want is a smaller four wheeled vehicle for driving about in the desert.   My original idea was to design and build horse drawn vehicles up there...   but life got in the way.   I still want a roebust Wagonette for her.   Something light enough to hitch a light horse to if and when I get an additional horse to keep her company.
